java實現(xiàn)類似百度文庫功能linu

1、實現(xiàn)類似百度文庫在線觀看功能目錄實現(xiàn)原理過程2資料和工具準備2工具準備和安裝2項目目錄及源碼6程序運行需要openoffice服務支持1810/19實現(xiàn)原理過程 網(wǎng)上大致看了下實現(xiàn)的方式,大體上有四種轉(zhuǎn)換的方式：1. Txt/Word/Excel/PPT=PDF(OpenOff ice+JodConverter)=SWF(pdf2swf)=FlexPap er瀏覽2. Txt/Word/Excel/PPT二PDF (MSOf f ice+JACOB)二SWF (pdf2swf)二FlexPaper 瀏覽-Txt/Word/ExceLPPT=SWF (FlashPaper)二FlexPaper

2、瀏覽4T-Txt/Word/Excel/PPT二SWF (print2flash)二)FlexPaper 瀏覽資料和工具準備工具OpenOfficeJodConverterSwftools(pdf 2swf)FlexPaper資料方面，大致搜索了百度文庫和開源中國上的一些資料，其實都大同小異。工具準備和安裝1 .安裝openoffice3,這個安裝過程很糾結(jié)，遇到過各種問題，因為先后在幾臺服務器上安裝過，最順利的安裝方法如下tar zxvf 00o_3 3. 0_Linux_x86-64_install-rpm-wJRE_zh-CN. tar. gzcd RPEMrpm -ivh *. rpm

3、 -nodeps - force安裝后的默認目錄是在：/opt/目錄下面啟動服務：/opt/openoff ice. org3/program/soffice -headless一accept二socket， host=127 0 0 1, port=8100;urp;/z -nof irststartwizard &2 .來安裝 openoffice sdktar zxvf 00o-SDK_3. 3. 0_Linux_x86-64_install-rpm_en-US. tar. gzcd 000330_m20_native_packed-l_en-US. 9567/RPMS/rpm -vih

4、 *. rpm3 . JODConverter其實不用安裝 解壓了就行安裝jodconverter. 2. 2. 2 ,安裝了這個之后就已經(jīng)可以實現(xiàn)DOC轉(zhuǎn)PDF 了。解壓，復制到一個目錄里面去，就能直接用了，調(diào)用它里面的/lib/jodconverter-cli-2. 2. 2. jar這個玩意兒就行，可以直接運行命令測試：java -jar /home/down1oad/jodeonverter-2. 2. 2/1ib/jodconverter-cli-2. 2. 2. jar/home/download/aaa. doc /home/download/1. pdf順利的話就直接可以轉(zhuǎn)成功

5、了exec (java -jar/home, down 1 oad,/jodconverter-2. 2. 2/lib/jodconverter-cli-2. 2. 2. jar/home, download/aaa. doc /home/down1oad/1. pdf)4 .
